High Fidelity (hifi) is an early-stage technology lab experimenting with Virtual Worlds and VR.
In this repository you'll find the source to many of the components in our alpha-stage virtual world. The project embraces distributed development and if you'd like to help, we'll pay you -- find out more at Worklist.net. If you find a small bug and have a fix, pull requests are welcome. If you'd like to get paid for your work, make sure you report the bug via a job on Worklist.net.
We're hiring! We're looking for skilled developers; send your resume to [email protected]
Interface is our OS X and Linux build-able client for accessing our virtual world.
Hifi uses CMake to generate build files and project files for your platform. You can download CMake at cmake.org
Create a build directory in the root of your checkout and then run the CMake build from there. This will keep the rest of the directory clean, and makes the gitignore a little easier to handle (since we can just ignore build).
mkdir build
cd build
cmake .. -G Xcode
Those are the commands used on OS X to run CMake from the build folder and generate Xcode project files.
If you are building on a *nix system, you'll run something like "cmake ..", which uses the default Cmake generator for Unix Makefiles.
If Cmake throws you an error related to Qt5 it likely cannot find your Qt5 cmake modules. You can solve this by setting an environment variable, QT_CMAKE_PREFIX_PATH, to the location of the folder distributed with Qt5 that contains them.
For example, a Qt5 5.1.1 installation to /usr/local/qt5 would require that QT_CMAKE_PREFIX_PATH be set with the following command. This can either be entered directly into your shell session before you build or in your shell profile (e.g.: ~/.bash_profile, ~/.bashrc, ~/.zshrc - this depends on your shell and environment).
export QT_CMAKE_PREFIX_PATH=/usr/local/qt/5.1.1/clang_64/lib/cmake/
The path it needs to be set to will depend on where and how Qt5 was installed.
After running cmake, you will have the make files or Xcode project file necessary to build all of the components. For OS X, load Xcode, open the hifi.xcodeproj file, choose ALL_BUILD from the Product > Scheme menu (or target drop down), and click Run.
If the build completes successfully, you will have built targets for all HiFi components located in the build/target_name/Debug directories.
In addition to CMake, Qt 5.1 is required to build all components.
What can I build on? We have successfully built on OS X 10.8, Ubuntu and a few other modern Linux distributions. A Windows build is planned for the future, but not currently in development.
Using Finder, locate the interface.app Application in build/interface/Debug, double-click the icon, and wait for interface to launch. At this point you will automatically connect to our default domain: "root.highfidelity.io".
If you don't see anything, make sure your preferences are pointing to root.highfidelity.io, if you still have no luck it's possible our servers are simply down; if you're experiencing a major bug, let us know by suggesting a Job on Worklist.net -- make sure to include details about your operating system and your computer system.
To move around in-world, use the arrow keys (and Shift + up/down to fly up or down) or W A S D, and E or C to fly up/down. All of the other possible options and features are available via menus in the Interface application.
assignment-client, animation-server, domain-server, pairing-server and space-server are architectural components that will allow you to run the full stack of the virtual world should you choose to.
In order to set up your own virtual world, you need to set up and run your own local "domain". At a minimum, you must run a domain-server, voxel-server, audio-mixer, and avatar-mixer to have a working virtual world. The domain server gives three different types of assignments to the assignment-client: audio-mixer, avatar-mixer and voxel server.
Complete the steps above to build the system components, using the default Cmake Unix Makefiles generator. Start with an empty build directory.
cmake ..
Then from the Terminal window, change directory into the build directory, make the needed components, and then launch them.
First we make the targets we'll need.
cd build
make domain-server assignment-client
If after this step you're seeing something like the following
make: Nothing to be done for `domain-server'.
you likely had Cmake generate Xcode project files and have not run cmake .. in a clean build directory.
Then, launch the static domain-server. All of the targets will run in the foreground, so you'll either want to background it yourself or open a separate terminal window per target.
cd domain-server && ./domain-server
Then, run an assignment-client with all three necessary components: avatar-mixer, audio-mixer, and voxel-server assignments. The assignment-client uses localhost as its assignment-server and talks to it on port 40102 (the default domain-server port).
In a new Terminal window, run:
./assignment-client/assignment-client -n 3
Any target can be terminated with Ctrl-C (SIGINT) in the associated Terminal window.
To test things out you'll want to run the Interface client. You can make that target with the following command:
make interface
Then run the executable it builds, or open interface.app if you're on OS X.
To access your local domain in Interface, open your Preferences -- on OS X this is available in the Interface menu, on Linux you'll find it in the File menu. Enter "localhost" in the "Domain server" field.
If everything worked you should see "Servers: 3" in the upper right. Nice work!
In the voxel-server/src directory you will find a README that explains in further detail how to setup and administer a voxel-server.
